How much does the 2023 Mercedes-Benz GLS cost?

Prices have softened 8.61% compared to this time last year, making it a favorable time to shop this model year.

Is the 2023 Mercedes-Benz GLS a good car?

The 2023 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is aimed at families that want the comfort and space of a luxury sedan with some off-road capability, and it does that while still feeling distinctly upscale. The GLS also has a reputation for being comfortable, with premium interior materials and easy-to-use technology among its strengths.

For 2023, the GLS450 gained a panoramic moonroof and metallic paint as standard equipment. Standard equipment included dual 12.3-inch displays with MBUX, navigation, a Burmester surround sound stereo, wireless charging, and three years of Mercedes Me Connect services, along with power-folding third-row seats and power-adjustable second-row seats.

For you, that means the 2023 GLS makes the most sense if you want a large, luxurious three-row SUV with a strong comfort-and-technology mix. 36.8% of listings are priced as good or great deals, which suggests there are still worthwhile opportunities if you shop carefully.

Is the 2023 Mercedes-Benz GLS reliable?

The 2023 Mercedes-Benz GLS is described as comfortable, upscale, and well equipped, with premium interior materials and easy-to-use technology among its strengths. It is also positioned as a large luxury SUV with broad appeal for families who want space and comfort.

That said, you should still think about long-term ownership risk carefully, because a large luxury SUV can be costly to maintain if prior care has been inconsistent.

What should I look for when buying a used 2023 Mercedes-Benz GLS?

Accident-free inventory is excellent at 90.7% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially on a luxury SUV with lots of technology and seating hardware. Focus on overall condition, signs of heavy family use, and whether the interior features, third-row access, and power-folding seats all work as intended.

Is now a good time to buy a used 2023 Mercedes-Benz GLS?

This is a moderate, selective buyer’s market, so you have room to compare listings and wait for the right one.

• Deal availability: 36.8% of listings are priced as good or great deals.
• Inventory: There are 1,191 listings available.
• Price trend: Prices have softened 8.61% compared with last year.
• Clean inventory: 90.7% of listings are accident-free.

If you find a listing below $65,211, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2023 Mercedes-Benz GLS's resale value?

The current average of $65,495 sits slightly below last year's $71,662.

That price movement suggests the market has already adjusted downward, which can help you buy with less risk of overpaying. If you plan to sell later, the softer trend means your resale outcome will depend heavily on mileage, condition, and how well the vehicle is equipped. A clean, well-kept example should hold up better than one with visible wear or a rough service history.

Should I buy a 2023 Mercedes-Benz GLS or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 36.8% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 90.7% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 8.61% compared with last year.

Consider the 2022 if:

• At $47,558, the 2022 costs less than the current year's $65,495 average.
• It emphasizes flagship luxury with a spacious, upscale cabin.

Consider the 2024 if:

• At $72,504, the 2024 costs more than the current year's $65,495 average.
• It adds refreshed styling, more standard equipment, and updated infotainment.

The bottom line: the 2023 is the best primary path if you want a strong mix of value, inventory depth, and luxury-SUV space. If price is your top priority, the 2022 is the better secondary path, while the 2024 makes sense if you want the newer refresh and are willing to pay more.
